Acute appendicitis continues to be a challenge in diagnosis and treatment during pregnancy. Maternal and fetal outcome was better than previously reported.

Nails are protective, thin, horny growth at the end of fingers and toes. Abnormalities of the fingernails and toenails can provide both subtle and obvious clues to common medical problems or severe systemic diseases. Inheritance, minor injuries, common habits, the use of cosmetics and a variety of infections account for many changes in the appearance of nails. Awareness of normal nail variants, abnormalities and their disease associations will be beneficial to detect systemic diseases.

, Constanza Beltrán M 1 . RESUMENSe presentan dos casos clínicos del Departamento de Otorrinolaringología de la Pontificia Universidad Católica de Chile, con diagnóstico de lipoma del conducto auditivo interno (CAI). Los lipomas del CAI son neoplasias benignas poco frecuentes, con una frecuencia de 0,15% de los tumores del CAI. Se presentan principalmente entre la tercera y quinta década de la vida, en su mayoría hombres caucásicos. Clínica y audiológicamente son indistinguibles de otros tumores de la misma zona, siendo el neurinoma del acústico (schwanoma vestibular) el tumor más frecuente en el CAI (90%). Las imágenes de resonancia magnética permiten realizar el diagnóstico específico de lipoma. El tratamiento quirúrgico ha sido desplazado por el manejo conservador, dado que los lipomas tienen crecimiento lento, sin trasformación maligna, en general, junto con difícil técnica quirúrgica por infiltración a estructuras adyacentes. Sólo estaría indicada la cirugía en casos que exista crecimiento tumoral durante el seguimiento o en pacientes con síntomas intensos y progresivos.Palabras clave: Lipoma, canal auditivo interno, resonancia magnética. ABSTRACTTwo case reports with diagnosis of internal auditory canal lipomas are presented. Lipomas of the internal auditory canal are benign neoplasms, making up 0.15% of all tumors in this area. They occur more frequently in the third to fifth decade of life predominantly in Caucasian males. The are clinically and audiologically indistinguishable from other tumors in this region, with eighth cranial nerve schwannomas (vestibular schwannomas) being the most common IAC tumor (90%). MRI findings allow for specific diagnosis of a lipoma. Regarding treatment, surgery has been displaced by a conservative treatment of this rare lesion. Lipomas are slow growth lesions, without malignant transformation, and with inherent difficulties to their removal because of the adipose tissue infiltrating the nerve, as well as only partial resolution of symptoms in most cases. Surgery could only be indicated when relevant and disabling symptoms are present.
